369		-##ChartMuseum is being deprecated. After the migration is complete, **all harbor charts will be removed from ChartMuseum**, and **old HTTP(S)-based chart repositories will no longer work in Rancher (for internal harbor charts)**.##
	371	+There are two ways to migrate your repositories:
370	370
371		-To ensure a smooth transition, we recomment should **add an OCI-based repository alongside the existing ChartMuseum repository** during the migration phase.
	373	+1. Direct Transition (Editing the Existing Repository)
	374	+ You can modify the existing repository directly:
	375	+11.Change the target to “OCI Repository”.
	376	+11.Update the URL as required (the repository name cannot be changed).
372	372
373		-We will make your charts available in the corresponding new `<pkey>-helm` OCI projects.
	378	+After saving, installed apps will automatically start using the updated repository.
374	374
375		------
	380	+Important limitation: OCI repositories must point directly to a single chart repository, not to a parent folder.
	381	+If your old repository included several charts (for example “bitbucket” and “jira”), then after switching to OCI you can only target one chart (e.g. “bitbucket”).
	382	+The other charts will no longer receive updates through this repo, and you will still need to create additional repositories for each individual chart.

381		-| **Old Repository** | The existing HTTP/HTTPS ChartMuseum repository. |
382		-| **New Repository** | The new OCI-based Helm chart repository created for your project (e.g. `<chart-repo-name>` in `<pkey>-helm`). |
	386	+This approach allows a smooth transition while the old ChartMuseum repository continues to function.
	387	+You can:

384		------
	389	+* Create a new OCI repository for each chart,
	390	+* Keep the old ChartMuseum repo enabled during the migration,
	391	+* Migrate applications gradually following the steps described in the main migration guide.
385	385
386		-## Why This Migration Is Required
387		-- ChartMuseum is deprecated and will be removed.
388		-- Applications deployed from old repos keep a reference to that repo inside their labels.
389		-- Without updating the application to point to the new OCI repo, **Rancher will not detect new chart versions**.##
	393	+This avoids disruptions and allows controlled migration.

	395	+Special Case: Old Repo Targeting Multiple Chart Repos
392	392
393		-## Migration Steps##
	397	+If your existing repository targets multiple chart repositories and you need the new OCI setup to behave the same way, please contact support. OCI does not support multi-chart endpoints within a single repository, and we can help you find an appropriate solution.

	418	+1. ##Create the New OCI Repository in Rancher##
	419	+11. Go to **Apps → Repositories**.
